Produktbeskrivning
ATMega328P är en enkel, men väldigt kapabel 8-bitars mikrokontroller från Atmel. Den har bla. 6 PWM-utgångar, 6 analoga ingångar, SPI- och I2C-interface.
Detta är samma version av microcontroller som används i Arduino UNO R3. Kretsen levereras utan Bootloader. För att kunna användas i Arduino AVR-projekt se filmlänkar med instruktioner hur man lägger in en Bootloader för Arduino samt vilka externa komponenter som behövs.
Kretsen fins att köpa förprogrammerad med Arduino Bootloader om man föredrar det (41010636).
